Dr. Cooper in studio, breast cancer updates; migrane information.

There is important news for women who are at an increased risk for breast cancer.  A drug used primarily to treat osteoporosis turns out to be as effective as Tamoxifen, but with fewer side effects.    If you suffer from migraine headaches, the odds are you are a pre-menopausal female and the crippling pain is associated with your monthly cycle.  Today we'll discuss a new study that offers suggestions for treatment and prevention of migraines.  Also a drug used to treat high blood pressure appears to reduce the frequency of headaches by over 80 percent.   Dr. Cooper takes calls.
